Selective dry-cow therapy (SDCT) became mandatory in Italy on 28 January 2022. During 2020, a group of farms involved in a milk quality program began a pilot experiment with SDCT in order to understand its challenges and to identify areas for procedural improvements. The aim of this study was to describe the challenges and results of the SDCT in early adopters' herds with a special focus on treatment compliance. Retrospective data from 1911 cows from 11 dairy herds were evaluated. Somatic cell counts, clinical mastitis (CM) history, and the California Mastitis Test (CMT) were used as criteria for SDCT. Based on the dairy herd improvement test results and CM history, 48% of all cows should have received antibiotic treatments and internal teat sealants. Adding the CMT at dry-off increased the percentage of antibiotic-treated cows to 62%, with relevant variation among farms. Concerning treatment compliance, 21% of the cows were "non-compliant", suggesting the importance of monitoring treatment compliance. In conclusion, even if commonly used selection criteria for antibiotic treatments were used, the need for more education and in-depth monitoring of the SDCT adoption process was clearly identified. Close collaboration and agreement between veterinarians and farmers are key for SDCT adoption success.
选择性干奶牛疗法（SDCT）于2022年1月28日在意大利成为强制性措施。在2020年期间，一群参与牛奶质量计划的农场开始了SDCT的试点实验，以了解其面临的挑战并确定程序改进的领域。本研究的目的是描述早期采用者牛群中SDCT的挑战和结果，特别关注治疗依从性。对来自11个奶牛群的1911头奶牛的回顾性数据进行了评估。体细胞计数、临床乳腺炎（CM）病史和加利福尼亚乳腺炎检测（CMT）被用作SDCT的标准。根据奶牛群改良检测结果和CM病史，所有奶牛中有48%应接受抗生素治疗和乳头内密封剂处理。在干奶时增加CMT检测后，接受抗生素治疗的奶牛比例增加到62%，各农场之间存在相关差异。关于治疗依从性，21%的奶牛“不依从”，这表明监测治疗依从性的重要性。总之，即使使用了常用的抗生素治疗选择标准，也明确发现需要对SDCT采用过程进行更多教育和深入监测。兽医和农民之间的密切合作与共识是SDCT成功采用的关键。
